Changes for this release (latest changes first, earliest changes last)

• grub.cfg: Added (ahci1) to list of devices for ISOLINUX parser (CD/DVD) (this is needed for the X200 docking station).
• grub.cfg: ISOLINUX parsing is now done on all USB partitions.
• grub.cfg: Automatically switched to /boot/grub/libreboot_grub.cfg on a partition, if it exists.
• libreboot_bin: added static ARM binaries for flashrom, cbfstool, ich9gen and ich9deblob (tested on beaglebone black).
• Flashrom: removed redundant Macronix flashchip definitions (for X200 owners).
• Flashrom: added whitelist for ThinkPad X200.
• X200: fixed uneven backlight (at low levels)
• ich9macchange (new script, uses ich9gen): for changing the default MAC address on X200 ROM images.
• ich9gen: added capability to change the default MAC address (and update the checksum)
• ich9deblob: added new utility ich9gen: this can generate a descriptor+gbe image without a factory.rom dump present.
• Modified ich9deblob to use a struct for Gbe, documenting everything.
• Massively updated the ich9deblob utility: re-factored everything completely.
• Enabled cstates 1 and 2 on macbook21. This reduces idle heat / power consumption.
• buildrom-withgrub: disabled creation of *txtmode*.rom for X200 (only framebuffer graphics work)
• Updated SeaBIOS (again)
• docs/install/#flashrom_x200: improve instructions
• Updated flashrom (again) - patches updated
• Updated GRUB (again)
• Updated coreboot (again)
• build-release: not all files were copied to libreboot_src. fix that.
• build-release: include cbmem (statically compiled) in libreboot_bin
• Documentation (X200): added software-based flashing instructions
• Documentation: remove all references to the bus pirate (replaced with BBB flashing tutorials)
• New board: ThinkPad X200S and X200 Tablet support added to libreboot
• build: automatically find board names (configs) to build for
• New board: ThinkPad X200 support added to libreboot
• coreboot-libre config (all boards): enable USB dongle log output (for BeagleBone Black)
• cleandeps: actually clean grubinvaders
• .gitignore: add powertop directory
• cleandeps: clean i945-pwm utility
• scripts (all): fix typos
• Documentation: general cleanup.
• builddeps-flashrom: reduce build commands to a single for loop
• scripts (all): replace unnecessary rm -Rf with rm -f
• docs/release.html: add lenovo g505s to the list of candidates
• .gitignore: add libreboot_bin.tar.xz and libreboot_src.tar.xz
• libreboot_bin.tar.xz: Include utils as statically linked binaries
  • This means that the user does not have to install build dependency or build from source anymore.
• deps-parabola (removed) Remove Parabola dependencies script. Will re-add later (properly tested)
• grub.cfg: Add more path checks to isolinux parser (more ISOs should work now)
• Update SeaBIOS
• x60flashfrom5 (new), for X60 users upgrading from 5th/early release
• Update flashrom
• Update GRUB
• Updated coreboot-libre
  • i945: permanently set tft_brightness to 0xff (fixes bug on X60 where turning up brightness at max would make it loop back to low brightness)
• getcb: Revert X60/T60 to legacy backlight controls
  • The ACPI brightness patches were abandoned and obsolete.
• grub.cfg: Only load initrd.img if it exists. Add rw to linux line (for ProteanOS)

• New links added to docs/security/x60_security and docs/security/t60_security
• lenovobios_secondflash: Warn if BUCTS is not present. (not a dealbreaker. Can just pull out nvram battery/coin).
• lenovobios_firstflash: Fail if BUCTS fails. (anti-bricking precaution)
• Removed obnoxious warnings from flashing scripts, improved documentation instead.
• scripts (all): add proper error checking (fail fast, fail early. Do not continue if there are errors)
• buildrom-withgrub: rename image to boardname_layout_romtype.rom
• buildrom-withgrub: don't move cbfstool, execute directly
• resources/utilities/grub-assemble: add French Dvorak (BEPO) keyboard layout.
• Documentation: add docs/hardware/x60_keyboard.html (show how to replace keyboard on X60/X60T)
• Documentation: major cleanup (better structure, easier to find things)
• docs/release.html: Remove Acer CB5 from list of future candidates.
  • Too many issues. Chromebooks are crippled (soldered RAM/storage/wifi) and have too many usability issues for the libreboot project.
• docs/linux/grub_cbfs.html Major cleanup. Usability improvements.
• flash (flashrom script): remove boardmismatch=force
  • This was put there before for users upgrading from libreboot r5 to r6, but also allows the user to flash the wrong image. For example, the user could flash a T60 image on an X60, thus bricking the system. It's almost certain that most people have upgraded by now, so remove this potentially dangerous option.
• Documentation: update compatibility list for X60T LCD panels.
• docs/release.html: add note about X60 Tablet board in X60/X60s
• docs/howtos/grub_boot_installer.html: small corrections
• docs/howtos/grub_boot_installer.html: improved readability, fixed html errors
• Documentation (macbook21 related): clean up
